Frameless liquid crystal display device

Abstract

A frameless liquid crystal display device includes a rear enclosure, a backlight module arranged inside the rear enclosure, a mold frame arranged on the backlight module and mounted to the rear enclosure, and a liquid crystal display panel arranged on the mold frame. The liquid crystal display panel has an upper portion that is mounted to the mold frame through a connection section, which includes an elongate base plate to which an elongate projection structure is mounted. The mold frame forms a recess receiving and fixing the connection section therein by screws so as to fix the connection section and the mold frame to the rear enclosure. The liquid crystal display panel includes a CF substrate forming a step with respect to a lower edge of a TFT substrate. A surface decoration is bonded to the step to assemble the liquid crystal display panel to the mold frame.
